<h3><a name="elementsSysinfo">SMBIOS System Information</a></h3>
<p>
Some hypervisors allow control over what system information is
presented to the guest (for example, SMBIOS fields can be
populated by a hypervisor and inspected via
the <code>dmidecode</code> command in the guest). The
optional <code>sysinfo</code> element covers all such categories
of information. <span class="since">Since 0.8.7</span>

The <code>sysinfo</code> element has a mandatory
attribute <code>type</code> that determine the layout of
sub-elements, with supported values of:
</p>
<dl>
<dt><code>smbios</code></dt>
<dd>Sub-elements call out specific SMBIOS values, which will
affect the guest if used in conjunction with
the <code>smbios</code> sub-element of
the <a href="#elementsOS"><code>os</code></a> element. Each
sub-element of <code>sysinfo</code> names a SMBIOS block, and
within those elements can be a list of <code>entry</code>
elements that describe a field within the block. The following
blocks and entries are recognized:
<dl>
<dt><code>bios</code></dt>
<dd>
This is block 0 of SMBIOS, with entry names drawn from
"vendor", "version", "date", and "release".
</dd>
<dt><code>system</code></dt>
<dd>
This is block 1 of SMBIOS, with entry names drawn from
"manufacturer", "product", "version", "serial", "uuid",
"sku", and "family". If a "uuid" entry is provided
alongside a
top-level <a href="#elementsMetadata"><code>uuid</code>
element</a>, the two values must match.
